The Nathan Aspinall Player-Edition K-Flex Flight and Shaft system’s design is inspired by the stealth and precision of the ASP serpent. Known as the "ASP" Nathan Aspinall’s unique design features a striking snake motif alongside his nickname, embodying his dynamic approach to the game.
 
The K-Flex system is crafted using an advanced injection moulding process, ensuring outstanding resilience to impact. This integrated all-in-one flight and shaft is designed to minimise bounce-outs, featuring a unique shaft section that flexes on impact for tighter dart groupings and smoother throws. With a universal 2BA thread, K-Flex is compatible with most darts, offering versatility and ease of use.
 
With K-Flex, players benefit from consistent 90-degree flight positioning, enhancing accuracy and stability during every game.
